Listen to all of Chico's audio briefings by selecting a mission, choosing "Briefing Files", then entering the Chico file library. Once you listen to all the tapes, select Extra Ops mode, and choose "[029] Item Capture". Start the mission, take care of the three guards, and destroy the item crate. Collect its items, but instead of going to the extraction point, move south to the beach at Playa del Alba. When you enter the beach, turn left, and go down the dock. Miller will notify you about a strange animal at this location. Run down the dock to find Trenya, from the Monster Hunter series. After the dialog, you will be able to access "[121] Hunting Quest: Rathalos" in Extra Ops mode. Successfully complete the mission to unlock additional Monster Hunter related missions.

Bonus costumes

Successfully complete the indicated task or mission to unlock the corresponding costume:

Swallow: Frequently use long-range weapons and favor taking down enemies with non-lethal force.

Whale: Frequently use weapons with explosive power and favor cooperating with allies to take down enemies with non-lethal force.

"Love Deterrence" song

View all of Paz's Diary entries. You will find out her final wish was to sing for the members of MSF and unlock the "Love Deterrence" (Koi No Yokushi Ryoku) song in the soundtrack.

Seeing women in their underwear

Get an "S" rank on the "Date With Paz" mission to see her in her underwear. Additionally, go to the "Staff Management" screen at Mother Base. Look for Amanda, Dr. Strangelove, and Cecile, then press Y(2) to see them in their underwear.

Paz's diary

Defeat the harder versions of the A.I. Bosses. You can find the diary tapes inside the A.I. pods when you collect the boards.

Defeating Pupa

This trick requires the Law or RPG, M16, rations, and supply marker. Wait until Pupa stops, then fire a rocket at the large cylinder console on its front. To avoid the electric shots, do not stop moving. When it launches its lighting rods, take out a few near you with the M16, then lay flat on the ground until the lighting stops and keep firing. If you are running low on rations and/or ammunition, use the supply marker to call in more. Once it is destroyed, fire a rocket at the hatch on top of its head. You need to take the "programs"; it does not matter which ones you take out.
